Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a whistleblower with a blowing lid at the pouring mouth, which blows by the action of steam ejection.

[0002]

[Prior Art]

 In the whistle blower, when hot water is boiled and the steam pressure in the body 43 exceeds a certain pressure, steam blows out from the whistle hole of the blowing lid 42 attached to the spout 41 to make a whistle sound. Has become.

Therefore, if there is a gap between the blowing lid 42 and the spout 41, and the steam leaks from the gap, the whistle does not sound well, so the blowing lid 42 does not emit steam to the spout 41. It must be in close contact so that it will not leak.

Therefore, as shown in FIG. 5, the rear end of the support arm 45 of the blowing lid 42, which is rotatably attached to the spout 41 by the support shaft 44, is pressed by the spring 46 to push the blowing lid 42 to the blowing lid 42. The blowing lid 42 is brought into close contact with the spout 41 by applying a rotational force about the support shaft 44.

[0005]

[Problems to be solved by the device]

 By the way, as the spring 46, a coil spring or a spring having a specific shape as shown in FIG. 5 is conventionally used. Therefore, the material cost of the spring is high.

In addition, when the spring 46 is incorporated, the spring 46 must be contracted to be housed in a narrow space behind the support arm 45, so that it is troublesome to mount the spring 46. is there.

Therefore, the present invention aims to reduce the material cost of the spring and facilitate the attachment of the spring.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, this invention uses a leaf spring as a spring, and forms a leaf spring insertion groove on the upper surface of the front mounting recess at the front end of the handle that covers the blowing lid support metal. The upper end of the leaf spring was inserted into and fixed in place.

[0009]

[Action]

 Since the leaf spring can be fixed by inserting it into the leaf spring insertion groove formed in the handle before attaching the handle, the leaf spring can be easily attached.

In addition, the material cost of the leaf spring is lower than that of the coil spring and the spring of a specific shape.

[0011]

【Example】

 An embodiment of this invention will be described below.

The whistle-blowing water heater has a pouring spout 1 provided with a blowing lid 2 that blows by a steam jetting action. In FIG. 1, reference numeral 3 is a body portion, 4 is a lid, and 5 is a handle.

At the upper end of the blowing lid 2, a support arm 6 that projects upward from the rear surface of the spout 1 and a finger hook 7 that projects forward and upward are formed. A shaft portion 8 is integrally formed on both sides of the tip of the support arm 6.

A blowing lid support fitting 9 is attached to the back surface of the spout 1.

The blowing lid support fitting 9 is formed by a lower surface plate 10, a pair of opposed side surface plates 11 formed by bending both sides of the lower surface plate 10 upward, and a rear end of the lower surface plate 10 being obliquely upwardly bent. The rear plate 12 is included. The bottom plate 10 is fixed to the back surface of the spout 1 by a rivet 13.

The upper side of the side plate 11 is notched obliquely forward, and the shaft locking claw 14 is formed by this notch, and the shaft portion 8 of the support arm 6 is formed in the shaft locking claw 14. It is designed to be locked by rotation.

A front mounting recess 15 is formed at the front end of the handle 5 so as to cover the blowing lid supporting fitting 9 mounted on the spout 1, and a front mounting recess 15 that opens to the front is formed. It is formed in such a size as to fit snugly between the rear plate 12 of the blowing lid support fitting 9 and the front part of the body 3.

A leaf spring insertion groove 16 is formed obliquely rearward on the upper surface of the front mounting recess 15, and an upper end of a leaf spring 17 is inserted into the leaf spring insertion groove 16. The leaf spring 17 inserted into the leaf spring insertion groove 16 has the leaf spring insertion groove 16 formed obliquely rearward, so that the lower end thereof projects obliquely forward and the rear of the support arm 6 of the sounding lid 2 It is mounted so that the end is pressed forward.

A locking projection 18 is formed in the center of one wall surface of the facing wall of the leaf spring insertion groove 16, and locking projections 19 are formed on both sides of the other wall surface. . The interval between the locking projections 18 and 19 on the opposing wall surfaces is formed such that the lower part is wide and the upper part is narrow. As a result, the leaf spring 17 can be easily inserted from below, and can be easily fixed by strongly inserting it upward.

A rear mounting recess 22 is formed at the rear end of the handle 5 above the rear surface of the body 3 so as to cover the mounting bracket 21 fixed by the rivet 20.

The assembling of the blowing lid 2 and the handle 5 is performed as follows.

First, the blowing lid support fitting 9 is fixed to the back surface of the spout 1 with the rivet 13. Next, the shaft portion 8 of the support arm 6 of the blow lid 2 is hooked and attached to the shaft locking claw 14 formed on the side plate 11 of the blow lid support fitting 9. Then, the leaf spring 17 is inserted and fixed in the leaf spring insertion groove 16 formed in the front mounting recess 15 at the front end of the handle 5, and the leaf spring 17 presses the rear end of the support arm 6 of the sounding lid 2. , The front mounting recess 15 of the handle 5 is covered on the blowing lid support fitting 9, and the rear surface of the front mounting recess 15 is provided between the rear surface plate 12 of the blowing lid support fitting 9 and the front surface of the body 3. Insert it. After that, the rear mounting recess 22 formed at the rear end of the handle 5 is covered on the mounting bracket 21, and the rear end of the handle 21 is fixed to the mounting bracket 21 with the bolt 23, whereby the mounting of the handle 5 is completed. To do.
